Not bad for a poor man's Carry On film, which has its moments. Good cast headed by Ted Ray, who I've always been a fan of - fond memories of his radio show Ray's A Laugh.
A number of Carry On regulars in this, the best one being Joan Sims as the dotty lady who does, and who manages to do most of her funny lines with a fag dangling from her mouth.
Worth a look, but don't expect too much.
